Using AI to Review a Paper: Can ChatGPT4o or Google NotebookLM Replace Reading the Real Thing?

While tech companies are pouring billions into their products to add AI-enabled features, the percentages of people who are using those features are mixed. Personally, I’ve made it a practice to use AI in some way every day and occasionally write an article using AI and comparing it to various sources, including my writing.

Last week, I read about the latest paper published by the Burning Glass Institute (BGI) and the Harvard Business School Project on Managing the Future of Work. Titled The Expertise Upheaval, co-authors Matt Sigelman, Joseph Fuller, Michael Fenlon, Erik Leiden, and Gwynn Guilford provide recent research and thinking about the impact of AI on the workforce.

Before I read the paper, I decided to load the PDF version into ChatGPT4o and ask for a 2,500-word overview highlighting the findings that impact higher education the most. I’ve appended its output below. Afterwards, you’ll find my comparative analysis after I read the paper, as well as my final thoughts.

The Expertise Upheaval and Its Implications for Higher Education

Overview

The report, published by the Burning Glass Institute in collaboration with Harvard Business School’s Project on Managing the Future of Work, analyzes how Generative AI (GenAI) will not primarily eliminate jobs but rather restructure the way expertise is acquired and rewarded. This “expertise upheaval” has direct consequences for institutions of higher education, which have historically served as gatekeepers and launchpads for careers in knowledge-intensive fields.

At the heart of the report is a novel distinction between two archetypes of work—Growth Roles and Mastery Roles—and the way GenAI will reshape their learning curves. These archetypes determine which careers will become harder or easier to access in an AI-enhanced economy. Understanding this shift is vital for higher education leaders who must adapt curricula, credentials, and talent pipelines to remain relevant and responsive.

Key Definitions and Frameworks

Growth Roles vs. Mastery Roles

• Growth Roles (e.g., legal associates, marketing specialists, project managers) involve careers where expertise accrues through progressive on-the-job experience, mentorship, and increasingly complex responsibilities.
  • These roles typically offer higher salaries and are more likely to require a college degree.
  • GenAI automates the foundational work that has historically served as a training ground.
  • This erodes the traditional career ladders—critical for both student progression and employer hiring.
• Mastery Roles (e.g., network administrators, data analysts, loan interviewers) involve front-loaded learning, often through formal education, and require immediate technical proficiency.
  • GenAI compresses the time needed to acquire basic proficiency.
  • This expands access by lowering the skill threshold to entry.

Implications for Higher Education

1. Disruption of Talent Pipelines in Degree-Dominant Fields

Growth Roles make up a significant share of the knowledge economy and are 51% more likely to require a bachelor’s degree. These roles also offer a 28% wage premium over Mastery Roles. As GenAI increasingly automates entry-level tasks in Growth Roles:

• College graduates face fewer traditional “foot-in-the-door” opportunities.
  • This threatens the value proposition of liberal arts and professional undergraduate degrees whose graduates rely on entry-level jobs to build expertise.
  • For example, marketing or legal graduates may find fewer internships and associate roles where skills were once honed.
• Institutions must redesign curricula to reflect higher expectations for graduates at the point of entry.
  • Traditional career ladders (e.g., junior copywriter to creative director) are being flattened.
  • Graduates will be expected to take on mid-level responsibilities earlier—with limited ramp-up time.

2. Rethinking Learning Models and Program Design

The shifting nature of expertise demands a fundamental transformation in how higher education develops talent:

• Simulated learning environments and experiential education must replace in-the-field apprenticeships.
  • Higher ed must use simulations, case-based learning, and project-based assessments to replicate lost entry-level tasks.
  • Example: a university marketing program may incorporate GenAI-enabled scenario planning where students manage a digital campaign end-to-end.
• Curriculum must emphasize judgment, strategy, and human-centric skills.
  • Since GenAI performs well on routine, codified tasks, institutions must train students in:
    • Strategic decision-making
    • Client and team management
    • Creative and critical thinking
    • Emotional intelligence

3. Credentialing for Mastery Roles: Shorter, Modular, and More Flexible

While Growth Roles are under threat, Mastery Roles offer opportunity—and colleges can seize on this:

• GenAI lowers the barrier to entry by guiding users through technical tasks (e.g., coding, data visualization).
• Higher ed institutions can respond by developing:
  • Microcredentials and certificates in high-demand technical domains.
  • Non-degree pathways that validate readiness through skills-based assessments.
  • Stackable programs that allow learners to enter the workforce faster and return for upskilling.
• Examples of in-demand Mastery Role credentials:
  • SQL/Data Warehousing certifications
  • AI-supported CAD design
  • Health informatics short courses

4. Impact on Admissions and Equity

• As the job market values experience over credentials in some roles and compresses learning curves in others, traditional four-year degrees may lose appeal—especially among:
  • Adult learners
  • First-generation students
  • Those seeking faster, cheaper pathways
• Higher ed will need to compete with:
  • Employer-based training programs
  • Bootcamps and alternative providers
  • On-the-job GenAI tools that reduce reliance on formal instruction
• Conversely, GenAI-enabled tools could democratize technical knowledge, allowing colleges to:
  • Broaden access to high-paying careers for historically marginalized populations
  • Reduce dependence on elite credentials by emphasizing skill attainment

5. Faculty Roles and Pedagogy Must Evolve

As students arrive with AI tools capable of handling rote or procedural tasks, the faculty’s value proposition must shift:

• Faculty become facilitators of wisdom, not just content deliverers.
• Instruction must:
  • Move from lecture to coaching and mentoring
  • Focus on capstone-style integrative learning
  • Require students to apply, defend, and critique AI-generated outputs
• New faculty competencies:
  • Designing assignments that cannot be easily outsourced to AI
  • Teaching how to collaborate ethically with AI
  • Guiding students in evaluating AI accuracy and bias

6. Employer Collaboration and Lifelong Learning

The erosion of traditional ladders in Growth Roles and expansion in Mastery Roles requires stronger education-employer partnerships:

• Institutions should co-design programs with employers, especially in:
  • Cybersecurity
  • Data analytics
  • Operations management
• Partnerships may include:
  • Apprenticeships
  • Embedded corporate projects
  • Co-branded credentialing (e.g., “AI Tools for Financial Analysts,” in partnership with a bank)
• Lifelong learning becomes a necessity, not an option:
  • Institutions must build lifelong customer relationships with alumni
  • Offer pathways to return for:
    • Mid-career specialization
    • AI-literacy training
    • Management upskilling

7. New Measures of ROI for Higher Education

The narrowing of entry-level Growth Roles challenges the return on investment for traditional college programs:

• With fewer pathways to economic mobility for recent grads, value-added must shift upstream:
  • Stronger alignment between academic learning and workplace readiness
  • Greater accountability for post-grad employment outcomes
• Institutions may need to:
  • Track graduate readiness for mid-level roles, not just job placement
  • Integrate AI-readiness metrics into program evaluation
• Expect greater scrutiny from:
  • Policymakers
  • Philanthropic funders
  • Prospective students

Strategic Recommendations for Higher Education Leaders

1. Audit Your Curriculum

• Classify programs by their alignment with Growth vs. Mastery Role trajectories.
• Identify entry-level learning opportunities at risk of automation.

2. Invest in Career Simulations and AI-Integrated Learning

• Replace lost experiential learning with structured GenAI-powered simulations.
• Develop case studies requiring AI-human collaboration and ethical decision-making.

3. Expand Credentialing for Mastery Roles

• Build stackable, short-form programs in areas where GenAI accelerates initial skill acquisition.
• Develop partnerships to credential adjacent skill pathways (e.g., journalism → data storytelling).

4. Rethink Advising and Admissions

• Provide transparent guidance on which majors face narrowing vs. widening opportunity fields.
• Tailor advising toward skills-first career mapping, not just degree paths.

5. Embrace Skills-Based Hiring and Learning Outcomes

• Work with employers to define real-world skill requirements.
• Design assessments and portfolios that validate those skills—potentially replacing course-based transcripts.

6. Build Infrastructure for Lifelong Learning

• Offer subscription models or alumni access to on-demand upskilling.
• Create “career resilience” centers to help alumni reenter evolving roles.

Conclusion: GenAI and the Future of Higher Education

The GenAI revolution is not just reshaping the labor market—it’s transforming the architecture of learning, talent development, and human capital. Higher education institutions that fail to adapt to the new contours of expertise—fewer traditional ladders, faster technical ramp-ups, more fragmented credentials—risk obsolescence.

But for institutions willing to innovate, GenAI presents a profound opportunity:

• To democratize access to high-wage careers
• To diversify pathways into the workforce
• To deliver value not just at age 18–22, but across a 40-year learning arc

The upheaval in expertise is not a threat to education—it is a call to transform it.

The Expertise Upheaval: What Generative AI Means for the Future of Higher Education

By Wallace E. Boston

As GenAI transforms the learning curve in the workplace, colleges and universities must rethink how they prepare students for a future where traditional entry points into professional careers are disappearing—and technical roles are opening to a broader talent pool.

Introduction: A New Challenge to Expertise

In July 2025, the Burning Glass Institute released a groundbreaking report titled The Expertise Upheaval: How Generative AI’s Impact on Learning Curves Will Reshape the Workplace. The report reframes the debate around automation and job loss, arguing that the most profound impact of Generative AI (GenAI) will be on how expertise is acquired—not just on whether jobs disappear.

This distinction has far-reaching consequences for higher education. Institutions of higher learning are the traditional gatekeepers of expertise. But GenAI is redrawing the path from novice to expert. As a result, some professional fields will become harder to enter without experience—experience now being automated away—while others will become more accessible because GenAI lowers technical barriers.

This article summarizes the key findings of the report and offers a higher education-focused interpretation of what colleges and universities must do to remain relevant, equitable, and valuable in a rapidly shifting labor market.

Two Archetypes of Work: Growth Roles and Mastery Roles

The report introduces a compelling framework that divides the U.S. workforce into two large occupational archetypes:

1. Growth Roles (Access Narrows)

• Examples: Legal associates, marketing specialists, project managers
• Characteristics:
  • Expertise builds progressively through experience
  • Learning curve: Gradual and accelerates over time
  • High reliance on on-the-job learning, mentorship, and apprenticeship
• GenAI impact:
  • Automates foundational tasks
  • Erodes traditional entry-level opportunities, which serve as stepping stones to seniority
  • Narrows access for new graduates and junior professionals

2. Mastery Roles (Access Expands)

• Examples: Data analysts, network administrators, loan officers
• Characteristics:
  • Expertise is front-loaded and codified
  • Learning curve: Steep at the start, then flattens
  • More amenable to rote study or formal training
• GenAI impact:
  • Compresses time to proficiency
  • Democratizes access to well-paying technical jobs by lowering skill acquisition costs

The Stakes for Higher Education

The two archetypes hold different economic implications—and pose distinct challenges for colleges and universities.

• Growth Roles pay 28% more on average than Mastery Roles and are 51% more likely to require a bachelor’s degree.
• Therefore, the GenAI-driven narrowing of entry points into Growth Roles hits college graduates the hardest, particularly those aiming for high-wage, knowledge-intensive careers.

This creates a paradox: as AI levels the playing field in technical fields, it raises the bar for graduates in traditional white-collar roles.

Implication 1: Disruption of Traditional Talent Pipelines

Colleges have long served as feeders into Growth Role pipelines—fields like law, business, marketing, and education administration. But as GenAI eliminates the foundational tasks in these fields, employers may skip junior hiring altogether and recruit experienced professionals only.

This shift creates:

• Fewer internships and associate roles for students and recent grads
• More pressure for graduates to arrive “mid-career ready”
• A decline in perceived ROI for bachelor’s degrees if first jobs disappear or stagnate

Implication 2: Curriculum Must Adapt to New Learning Curves

The erosion of entry-level training necessitates that higher education redesign learning experiences to replicate the lost “apprenticeship phase.” Specifically:

• Simulations, capstones, and AI-enhanced experiential learning must become central
• Assignments should emphasize:
  • Strategic thinking
  • Judgment under uncertainty
  • Team leadership and client management
• Curriculum must also emphasize skills GenAI cannot replicate:
  • Emotional intelligence
  • Contextual reasoning
  • Adaptability and ethical decision-making

Implication 3: New Value Proposition for Mastery-Oriented Credentials

As GenAI expands access to Mastery Roles, colleges have an opportunity to deliver short-form, modular credentials that train for entry-level proficiency in:

• Data warehousing
• Health informatics
• Cybersecurity
• Telecommunications
• CAD and technical design

Higher education institutions can:

• Develop certificate programs and microcredentials
• Offer non-degree pathways into high-demand roles
• Serve adult learners and career switchers seeking fast, AI-augmented upskilling

Implication 4: Increased Pressure to Demonstrate ROI and Outcomes

The disruption of traditional job ladders also disrupts the link between degrees and careers. Colleges will face increasing demand to show:

• Career readiness at graduation
• Placement into roles not easily automated
• Skills-based assessments that reflect AI-era competencies

Institutions may need to move away from credit-hour models and toward competency-based validation tied to employer needs.

Implication 5: Equity, Access, and the Democratization Opportunity

While Growth Roles narrow, Mastery Roles expand—particularly for non-traditional students. GenAI can serve as a great equalizer, lowering the barriers for:

• Low-income learners
• First-generation college students
• Adults re-entering the workforce
• Minorities historically excluded from tech roles

This is a moment for higher education to:

• Invest in inclusive technical programs
• Build bridges from liberal arts to tech through GenAI tools
• Partner with employers to credential adjacent skill sets

Implication 6: Rethinking Faculty Roles and Instructional Models

As students use GenAI tools for content generation and coding, faculty roles must evolve:

• From content delivery → learning facilitation
• From lectures → problem-solving labs
• From grading output → evaluating process and judgment

New faculty skills:

• Integrating AI into assignments ethically
• Coaching students on how to prompt, assess, and iterate with GenAI
• Designing collaborative learning experiences with humans and machines

Implication 7: Lifelong Learning and Industry Collaboration

The future of work is continuous reinvention. Higher education must pivot from a one-time experience to an ongoing relationship with learners. This includes:

• Alumni upskilling subscriptions
• Short courses for mid-career pivots
• Corporate training partnerships
• Embedded credentialing inside degrees

GenAI makes career progression non-linear. Colleges must match this with flexible, reconfigurable educational offerings that support fluid learning paths.

Strategic Actions for Higher Education Leaders

Goal	Action
Protect ROI of degrees	Redesign majors with AI-era entry roles in mind
Rebuild lost career ladders	Simulations, scenario-based learning, cross-functional capstones
Seize Mastery Role opportunity	Launch modular programs in tech, logistics, and data
Foster equity and inclusion	Expand access to credentials that bypass traditional gatekeeping
Prepare faculty	Train instructors to use and critique AI tools pedagogically
Embrace lifelong learning	Develop learning ecosystems for alumni and working adults

Conclusion: Education in the Age of AI

The Expertise Upheaval reminds us that education is not merely about transferring knowledge—it’s about shaping how that knowledge becomes expertise in practice. As GenAI redefines how expertise is built, higher education must rise to the occasion.

Some institutions will cling to traditional models, hoping the storm will pass. Others will embrace this transformation as an opportunity to:

• Close equity gaps
• Align more closely with evolving labor markets
• Reimagine learning as a lifelong pursuit

In this new world, learning curves are no longer fixed—they are malleable, AI-accelerated, and increasingly personal. Higher education’s challenge is to make them not just navigable, but empowering.

Analysis Indicates Issues

At this point, I stopped inputting prompts to ChatGPT and reviewed its output. While I was impressed with its speed (the ingestion of the PDF and creation of the output took less than one minute), I was not happy with the 1,200-word document. I asked ChatGPT for 2,500 words and it indicated that it had provided me with a 2,500-word summary.

I was surprised to receive a “new-to-me” follow-up from ChatGPT asking if I would like a version “formatted for publication.” I indicated that I would, and when it provided me with the publication-ready article, it indicated that it was 2,500 words. Sadly, it was about 1,200 words. 

Again!

At this point, I decided I was not ready to create a detailed comparison of the AI-generated summary with my personal thoughts. Instead, I opted to load the PDF into NotebookLM, a Google product. For those of you who have not used NotebookLM, it’s more of a tool with features than a highly customizable product based on variable prompts. I asked for a briefing doc and received the following output (fonts were adjusted by me).

The Expertise Upheaval: How Generative AI’s Impact on Learning Curves Will Reshape the Workplace

Executive Summary

This report, published in July 2025, analyzes how Generative AI (GenAI) will redefine career pathways and talent development, arguing that its primary impact will be on the “level of expertise required” for jobs rather than widespread job displacement. The study introduces two contrasting categories of roles based on their learning curves: Growth Roles and Mastery Roles, which collectively employ almost 50 million U.S. workers. GenAI’s effects on these roles are divergent, creating both narrowing and expanding access to career opportunities.

Key Findings:

• Impact on Expertise Levels: GenAI’s most significant influence will be on “the level of expertise required” for various roles, not merely the number of jobs. This fundamentally alters how knowledge and skills are acquired and how productivity grows over time.
• Two Archetypes of Roles: Growth Roles (Access Narrows): Characterized by learning that “intensifies significantly over time as workers take on more nuanced and judgment-heavy responsibilities.” GenAI automates foundational tasks, traditionally serving as training grounds, leading to “a narrowing of career entry points and a breakdown in conventional talent pipelines.” These roles, such as legal associates, marketing specialists, and project managers, employ approximately 18 million U.S. workers (12% of the labor force) and typically “command significantly higher compensation—paying 28% more on average than Mastery Roles, a difference of $20,000 annually—and are 51% more likely to require a college degree.”
• Mastery Roles (Access Expands): Defined by “front-loaded learning curves, requiring mastery of a body of codified technical knowledge at the start.” GenAI acts as an “equalizer, compressing the time required to gain initial proficiency and enabling more individuals to qualify for such positions.” Examples include network administrators, data warehousing specialists, and loan interviewers. These roles employ approximately 29 million U.S. workers (19% of the workforce).
• Economic Disparities: The disruption primarily affects higher-paying Growth Roles, suggesting GenAI “may serve to narrow career entry points for the college-educated workforce, potentially restricting access to some of the more lucrative career pathways in the knowledge economy.”
• Implications for Organizations: Workforce Structures: Traditional “pyramid-shaped workforce models” in knowledge economy roles (Growth Roles) may shift to “flatter or diamond-shaped structures, with fewer entry-level roles and more experienced specialists.”
• Talent Development: For Growth Roles, employers must “invest in alternative career ladders, including simulated training environments, structured mentorships, and modular upskilling programs that replicate lost opportunities for on-the-job learning.”
• Talent Acquisition: For Mastery Roles, organizations can “expand access by recruiting from adjacent fields, reducing reliance on degree-based hiring, and using GenAI tools to identify high-potential candidates and to support them in acquiring necessary expertise.”
• Call to Action: Employers, educators, and policymakers must “rethink how careers begin—and how they progress.” Success hinges on designing systems that “foster learning, recognize potential, and adapt to these new contours of expertise.”

Main Themes

 

1. The Redefinition of Expertise and Learning Curves by GenAI

The core argument of the report is that GenAI’s impact is less about outright job replacement and more about how “GenAI changes how workers progress along the learning curve itself.” It alters the fundamental pathway of skill acquisition and value creation in occupations.

• Learning Curve as a Key Factor: The “learning curve” is identified as the central concept for understanding GenAI’s workforce impact. This curve “represents the path workers follow as they acquire expertise—starting as novices; gaining fluency through repetition and feedback; mastering tasks; and growing in judgment, creativity, and strategic thinking.”
• Automation of Foundational Tasks: In Growth Roles, GenAI “automates foundational work that historically served as the training ground for future expertise,” thereby “removing critical rungs from the career ladder.”
• Acceleration of Proficiency: In Mastery Roles, GenAI acts as an “accelerant—compressing the time to proficiency by providing real-time guidance, instant access to specialized knowledge, and troubleshooting support.” This “lowering barriers to entry and making technical roles accessible to a broader range of candidates.”

2. Divergent Impacts on “Growth Roles” and “Mastery Roles”

The report categorizes occupations into two primary archetypes based on how their learning curves are affected by GenAI.

• Growth Roles (Access Narrows):
• Characteristics: Learning progresses “gradually [and then] accelerating,” with expertise being “Implicit, acquired through experience.” Entry-level task automation is “High.”
• Examples: Legal Associates, Project Managers, Marketing Specialists, Financial and Investment Analysts, Computer Systems Engineers/Architects.
• Impact: “Eliminates traditional entry-level learning opportunities.” The automation of early, routine tasks diminishes opportunities for junior staff to develop foundational skills, leading to a “narrowing of career entry points.” This creates a “greater relative importance to the capabilities of those with experience.”
• Economic Implication: These roles are “significantly better paying, with average salaries that are 28% higher” than Mastery Roles. GenAI “will disproportionately restrict entry points to high-value careers.”
• Quadrant Analysis (Figure 4): Flattened Pyramids: High junior share and high reduction in entry-level need (e.g., Market Research Analysts, Marketing Specialists, Sales Representatives). Traditional apprenticeship models are most at risk.
• Severed Pathways: Low junior share but high reduction in entry-level need (e.g., Actuaries, Computer Programmers, Web Developers). AI threatens to eliminate the few existing entry-level opportunities.
• Mastery Roles (Access Expands):
• Characteristics: Learning curve is “Steep initially → plateauing,” with expertise being “Explicit, codifiable, domain-specific.” Entry-level task automation is “Low.”
• Examples: Data Warehousing Specialists, Network Administrators, Loan Interviewers, Computer Numerically Controlled Tool Programmers, Rehabilitation Counselors.
• Impact: “Accelerates skill development by providing intelligent support tools.” GenAI can “compress years of training into immediate, accessible capabilities,” thereby “Democratizes access by reducing barriers to entry.”
• Economic Implication: While employing more workers, these roles generally “command significantly lower compensation.”
• Quadrant Analysis (Figure 6): Breaking Down Barriers: High barriers to entry with high potential for AI access enablement (e.g., Software Developers, Management Analysts, Network and Computer Systems Administrators). GenAI’s greatest democratizing potential.
• Pushing on an Open Door: Low barriers to entry but high potential for AI enablement (e.g., Computer User Support Specialists, Data Entry Keyers). AI primarily compresses learning curves for newcomers.

3. Profound Implications for Workforce Development and Organizational Strategy

The report emphasizes the need for a fundamental shift in how businesses, workers, educators, and policymakers approach talent in the age of AI.

• Organizational Structure Changes: In Growth Roles, the traditional “pyramid-shaped workforce models—with many juniors supporting a few seniors—may give way to flatter or diamond-shaped structures, with fewer entry-level roles and more experienced specialists.” This could lead to fewer opportunities for management experience.
• Shift from Talent Acquisition to Retention (Growth Roles): As expertise becomes scarcer and more concentrated, companies must move “away from a ‘churn-and-burn’ model of talent acquisition toward one more focused on investing in and retaining workers with scarce expertise.”
• New Training Models (Growth Roles): Employers will need “new training models that accelerate learning,” potentially including “simulations” to replicate lost on-the-job experience. Focus will shift to “boosting the productivity of existing employees” and “identifying and cultivating skills that are unique to their context.”
• Skills-Based Hiring (Mastery Roles): To capitalize on expanding access, businesses “must adopt hiring and training strategies that realize the potential of AI to broaden access.” This includes leveraging “AI-powered skill mapping and talent analytics tools” and shifting “away from traditional credential-based hiring criteria” towards “demonstrated capability.”
• Broader Ecosystem Adaptation: Workers: Need to focus on “regular upskilling, cultivating adaptability, and advocating for their unique capacity to add value.”
• Educators: Must “transform traditional learning models,” preparing students for “entry-level positions that are more demanding than in the past.”
• Policymakers: Play a critical role in “shaping the workforce development ecosystem” through funding, training initiatives, and public-private partnerships.

Most Important Ideas/Facts

• GenAI’s primary impact is on expertise, not job numbers: “GenAI’s biggest impacts won’t be on the number of jobs so much as on the level of expertise required to do them.”
• The “learning curve” is the analytical lens: Understanding how GenAI “reshapes learning” is crucial to predicting its effects.
• The 18 million U.S. workers in Growth Roles face narrowing access: These roles are “disproportionately affected” by AI’s impact on entry points and are generally “higher-paying” ($20,000 more annually, 28% higher average salary) and “51% more likely to require a college degree.”
• The 29 million U.S. workers in Mastery Roles see expanding access: These roles benefit from GenAI democratizing “complex domain knowledge” and accelerating initial proficiency.
• Economic mobility and higher education returns are at stake: GenAI’s impact on Growth Roles “disproportionately affects college-educated workers seeking access to the most economically rewarding careers.”
• Shift in organizational models: From “pyramid-shaped” to “flatter or diamond-shaped structures” with fewer junior roles.
• Importance of implicit vs. explicit knowledge: GenAI excels at codified, “explicit knowledge,” making Mastery Roles highly amenable to augmentation. It is “far less capable of replicating” “implicit knowledge” (intuitive, experiential) found in many Growth Roles.
• New talent strategies are essential: Companies need to redesign career ladders, focus on retention of experienced staff, and implement skills-based hiring for different role types.
• Methodology based on wage dispersion: The study uses wage dispersion as a proxy for the steepness of learning curves and combines it with GenAI exposure scores to classify occupations.

At this point, I opted to go no further. I thought about asking a different AI tool to compare the ChatGPT summary with the NotebookLM summary after ingesting the original paper pdf but determined that I would leave an exercise like that for another day. I noted that the NotebookLM Briefing Doc provided me with a 1,500-word document, more words than the ChatGPT output.

 

My Thoughts About the Outputs Compared to the Paper

There is no ideal comparison between a summary, regardless of who or how it is generated, and the original. Using the summary to describe a paper is like using Cliff Notes to describe a book. A reader may get the highlights, but a summary cuts out much of the original context and flow, and LLMs cut out the charts. Half of this 41-page paper includes data tables relevant to the findings.

I noted that ChatGPT omitted the fact that the category of Growth Workers represents 1 in 8 US workers (17.8 million total). It also omitted the numbers for the Mastery Workers – 1 in 5 US workers (28.6 million total). NotebookLM included these numbers in its briefing doc.

Because I prompted ChatGPT4o to focus on the implications for higher education, some of the paper’s comments regarding implications for employers and policymakers were not included. Mea culpa. It’s likely for this reason that the NotebookLM briefing document more closely paralleled the findings from the original paper.

I also noted that the researchers’ comments about the paper’s key limitations were not included in the summary. I thought this sentence from the paper provides an excellent insight:

“Most fundamentally, uncertainty about GenAI’s future capabilities and the speed of adoption make it hard to forecast the magnitude and timing of its impact, as well as how those might interact with demographic trends or other structural forces shaping the US labor market.”

In other words, higher education institutions might have time to prepare their students for these shifts, or might not have time to prepare their students/graduates. This is a big caveat and one that was missed.

The researchers’ methodology was not described in either paper. While a one-page description of the methodology is included in Appendix A of the paper, a brief methodology is included in the main flow and represented by the following illustration, which I would have included had I written a post that focused on my review of the paper without using an AI tool.

While the number of occupations examined appears low, it’s important to note that the researchers wrote that the database utilized includes 99 percent of all jobs posted in the US over the past two years.

Not mentioning anything about the research methodology is concerning, particularly when methodologies may “pre-determine” outcomes. Researchers familiar with the Burning Glass Institute database may be more informed than outsiders. When I read the more detailed explanation of the methodology in Appendix A, the authors referred me to another research paper that they used to determine which of the occupations they would select. In case you skimmed over the diagram above, they narrowed down tens of thousands of occupations to 273.

The referenced paper, co-authored by Tyna Eloundou, Sam Manning, Pamela Mishkin, and Daniel Rock and published in August 2023, has been cited more than 1,200 times. Had I been asked to write a peer review of the newer paper, I would have read the Eloundou, Manning, Mishkin, and Rock paper since I was not familiar with the methodology they originated. Those researchers indicated that a weakness was that the evaluators of the occupations for the weighting process were people with skills in LLM’s and not professionals from given fields. They indicated that future research might be more precise if occupational professionals were utilized in the weighting process.

Another nuance to the report that is not included in the summary is the report’s explanation of why learning curves were selected. Simply put, much of the previous research focused on AI’s potential to automate tasks and replace human effort. The report’s authors wrote that their “research finds that GenAI changes how workers progress along the learning curve.”

Under the well-utilized theorem that “a picture says a thousand words,” the graphics utilized by the researchers are important in understanding the underlying research findings. None of those figures and tables were included in either AI summary. Naturally, the authors have a sequencing of figures that align with their explanation of the findings.

Figure 1 below illustrates the analysis of many different occupations, showing how AI changes the balance of barriers to entry versus the value of expertise. The four outcomes of Widening Spread, Widening Access, Shrinking Fields, and Raising the Bar are not specifically discussed in the summary.

The authors’ next figure illustrates the rise in earnings over time for certain occupations. As the header states, this provides an understanding of why widening access or shrinking the field by using AI would impact the learning curve and earning curve for a specific occupation.

Since it’s my understanding that current GenAI tools do not have the capability to analyze a figure or a chart, I am not sure how they handle the text related to either of those. In Figure 4 below, the researchers illustrate the four distinctive ways that AI can impact the role of junior-level employees.

Flattened Pyramids exist when occupations combine a high junior share with a high reduction in need for entry-level talent. Severed Pathways exist when occupations have a low junior share but face a high reduction in need for entry-level talent.

Traditional Hierarchies Persist when occupations have a high junior share but face only a modest AI impact on entry-level work. Lower Impact/Incremental Adaptation are the occupations least impacted by AI-driven changes to entry-level work and will see only incremental adaptation.

Naturally, a similar figure was created for Mastery Roles. In Figure 6 below, you can see the four patterns for occupational impact. There are four dynamics of occupations in Mastery Roles as well.

Breaking Down Barriers occupations combine high barriers to entry with high potential for AI access enablement. The researchers maintain this quadrant represents GenAI’s greatest potential for reducing traditional barriers to entry.

Pushing on an Open Door roles have low barriers to entry but high potential for AI enablement. 

Low Returns to AI occupations have both low barriers to entry and modest benefits from AI. Customer Service Reps would be an example of an occupation in this quadrant.

Barriers Persist occupations combine high barriers to entry with limited projected AI impact. Construction Managers would be an example of an occupation in this quadrant.

 

Final Thoughts

All in all, I believe this was a worthwhile exercise. Using ChatGPT4o to summarize the paper and analyze findings that pertained to higher education was reasonable, particularly given the quick response (less than one minute). 

Using NotebookLM to provide a briefing document gave me an opportunity to see how it performed without options to tweak the outcome like ChatGPT. The two summaries are very different, with the ChatGPT4o emphasis on higher education. I’ll remember the differences as I consider future use of both tools.

While both tools performed their functions quickly, neither was a replacement for reading the research paper in its entirety. From my academic background, I am always interested in the methodology used for data analysis. As I outlined earlier, neither AI-generated summary mentioned the methodology at all. I may or may not be interested in the detailed tables (16 pages) published in the Appendix.

I utilized a few of the figures published by the authors to demonstrate the development and transition of findings as displayed in the report. It’s my understanding that GenAI products have not reached the level of analyzing figures and tables in reports and including that analysis in summary analysis and commentary. Until then, it’s another reason to value the original human-generated report.

Lastly, as I wrote this analysis and summary, I decided to go back to ChatGPT4o and see what it would have written had I not asked it for an emphasis on higher education. If you are interested in seeing what it generated, it is appended below. I think it is a concise and accurate summary, but again, it only wrote approximately 1,500 words.

You said:   Could you provide me with a 2,500 word summary of the same pdf without any specific focus on higher education or any topic other than what is mentioned in the article?

ChatGPT wrote:   Certainly. Below is a comprehensive 2,500-word summary of The Expertise Upheaval: How Generative AI’s Impact on Learning Curves Will Reshape the Workplace (Burning Glass Institute, July 2025). This summary remains faithful to the report’s full scope and framing—without narrowing the focus to higher education or any other specific domain.

Summary of “The Expertise Upheaval: How Generative AI’s Impact on Learning Curves Will Reshape the Workplace”

Burning Glass Institute, July 2025

Executive Overview

The report challenges prevailing narratives about artificial intelligence (AI) and job loss, asserting that the core transformation driven by Generative AI (GenAI) is not job elimination but a restructuring of how expertise is developed. GenAI fundamentally changes career learning curves, especially the early phases where workers traditionally gain hands-on experience, mentorship, and fluency through routine tasks.

Rather than eliminating entire occupations, GenAI is disrupting the pathways by which individuals gain expertise, which in turn is reshaping how organizations acquire, train, and retain talent. The report identifies two distinct occupational archetypes—Growth Roles and Mastery Roles—each experiencing dramatically different impacts from GenAI.

Key Concepts: Learning Curves and Expertise Pathways

The central analytical frame of the report is the learning curve, which illustrates how expertise and productivity are acquired over time.

• In some occupations, learning is progressive and experience-based—workers grow into expert roles by starting with foundational tasks and gradually taking on more complex work.
• In others, proficiency is front-loaded—a large portion of required knowledge must be mastered at the outset, with fewer gains from tenure.

GenAI reshapes both kinds of curves. It compresses front-loaded learning curves and hollows out experience-based ones, thus altering how and when workers gain critical knowledge.

Growth Roles vs. Mastery Roles: Two Archetypes of Work

1. Growth Roles

• Learning curve: Starts gradually and accelerates over time
• Characteristics:
  • Workers build judgment and strategic ability through exposure, mentorship, and incremental complexity.
  • Entry-level tasks often serve as apprenticeships or foundational stepping stones.
• Examples: Legal associates, marketing specialists, project managers, analysts, paralegals
• GenAI Impact:
  • Automates entry-level tasks, eliminating key steppingstones
  • Disrupts traditional talent pipelines
  • Reduces opportunities for new entrants to gain the experience required for advancement
• Employment footprint: ~18 million U.S. workers (12% of the labor force)

2. Mastery Roles

• Learning curve: Steep at the outset, then plateaus
• Characteristics:
  • Workers must master complex but codified technical skills upfront.
  • Expertise accrual after baseline proficiency is relatively modest.
• Examples: Data analysts, network administrators, loan interviewers, CAD technicians
• GenAI Impact:
  • Reduces barriers to entry
  • Accelerates time to proficiency
  • Expands access to well-paying roles for more individuals
• Employment footprint: ~29 million U.S. workers (19% of the labor force)

The Divergence and Its Consequences

Though Mastery Roles employ more people, Growth Roles pay 28% more on average and are significantly more likely to require a college degree. Consequently, GenAI may democratize access to technical occupations while making access to higher-paying, judgment-intensive roles more exclusive.

This divergence presents a workforce paradox:

• Fewer rungs on the ladder in high-value, cognitively intensive careers
• More ramps into technical roles via AI-enabled learning and automation

The Economic and Organizational Implications

Workforce Structures Will Shift

• Traditional organizational models (pyramids with many junior staff feeding into fewer senior roles) may evolve into diamond-shaped structures with fewer entry-level positions and a concentration of mid-level specialists.
• Companies may find it harder to cultivate internal leadership as fewer workers gain experience over time.

Learning & Development Must Be Reimagined

• Foundational training once delivered via real-world, entry-level experience must be replicated through simulation, mentorship programs, and structured learning.
• Employers must invest in modular upskilling, adaptive learning platforms, and AI-powered knowledge-sharing tools to grow talent internally.

How GenAI Impacts the Two Archetypes

Growth Roles: Erosion of Entry Points

GenAI excels at automating entry-level tasks like data compilation, content drafting, legal research, and project tracking. But these are precisely the tasks that junior employees use to build foundational skills.

Examples:

• Project Managers: Traditionally learn via coordinating tasks and producing reports; GenAI now automates much of that.
• Marketing Specialists: Tasks like market research, SEO writing, and data analysis are increasingly AI-enabled.

Without this early experience:

• Employers struggle to develop senior talent.
• Employees face barriers to career advancement.

Mastery Roles: Compression of Learning

GenAI reduces the time and effort required to gain initial proficiency in many technical roles.

Examples:

• Data Analysts: Can now use GenAI to write SQL queries, clean data, and generate dashboards without years of training.
• Web Designers: Can build visually polished websites using GenAI-driven code or no-code platforms.

In these fields, GenAI serves as an equalizer, enabling:

• Quicker workforce entry
• Easier career switching
• Broader inclusion of workers without formal credentials

The Four Quadrants of AI Impact

The report maps occupations along two axes:

• Barrier to entry (low → high)
• Value of accumulated expertise (low → high)

This creates four quadrants:

Quadrant	Description	Implication
Raising the Bar	High entry barriers, high value of expertise	Career entry becomes harder; senior talent more valuable
Widening Access	Lowers entry barriers while still rewarding experience	Opportunity for career mobility and democratization
Shrinking Fields	Higher barriers, but declining return on expertise	Likely decline in demand or viability
Widening Spread	Lower entry barriers, but steep rise in value of experience	Competition increases as gaps between novice and expert widen

The report focuses primarily on Raising the Bar and Widening Access, which affect nearly 50 million workers combined.

Wage Dispersion as a Proxy for Learning Curves

To identify where AI will have the greatest impact, the researchers analyzed:

• Wage dispersion within roles (i.e., difference between entry-level and senior pay)
• Task exposure to GenAI, especially for junior roles

This revealed that in Growth Roles with high wage dispersion, junior tasks are often highly automatable, creating a dangerous mismatch: AI can do the early work, but there’s no clear path to gain the experience needed for higher levels.

Occupations Most Affected

Growth Roles Most Disrupted

• Project Management Specialists
• Training and Development Managers
• Marketing Specialists
• Public Relations Specialists
• Actuaries
• Financial Risk Specialists
• Operations Research Analysts
• Web and Digital Interface Designers
• Tutors

These fields require new career ladders, as GenAI erodes the traditional route to mastery.

Mastery Roles Poised for Democratization

• Data Warehousing Specialists
• Electrical and Electronics Drafters
• Computer Numerically Controlled (CNC) Tool Programmers
• Database Architects
• Network and Computer Systems Administrators
• Eligibility Interviewers
• Civil Engineering Technicians
• Telecommunications Specialists

These roles are more explicit knowledge-based, and GenAI can support their tasks through real-time coaching, data retrieval, and code generation.

Rewriting Talent Strategy

To stay competitive in the AI era, organizations must:

1. Redesign Organizational Structures

• Embrace flatter hierarchies with fewer junior roles
• Promote cross-functional teams
• Adapt role design to emphasize mid-career contributions

2. Rethink Training and Onboarding

• Replace lost on-the-job learning with simulations and guided mentorship
• Focus training resources on experienced workers and lateral talent acquisition
• Build firm-specific knowledge systems (e.g., AI-enhanced wikis, learning platforms)

3. Shift from Acquisition to Retention

• With fewer entry points, organizations must invest in:
  • Keeping experienced workers
  • Identifying internal potential
  • Developing alternative career ladders

4. Embrace Skills-Based Hiring

• Replace degree and credential screening with skills assessments, portfolios, and practical tests
• Use AI tools to identify adjacent skill sets from other roles or industries
• Prioritize reskilling and upskilling over traditional recruitment

AI-Driven Inclusion and Career Mobility

GenAI can reduce the “paper ceiling” by:

• Allowing workers from nontraditional backgrounds to enter high-skill fields
• Supporting career switches by compressing skill acquisition time
• Reducing reliance on traditional education and credentialing

This potential must be supported by:

• Public-private partnerships
• Targeted reskilling programs
• Policy reforms to expand access to postsecondary training and credentialing

Limitations and Caveats

The report acknowledges several limitations:

• Projections are based on current capabilities of LLMs (Large Language Models), and do not include robotics or domain-specific AI tools.
• It does not estimate net employment changes, only the impact on career pathways.
• Data is U.S.-focused but potentially applicable to other developed labor markets.

Conclusion: A New Paradigm for Work and Learning

GenAI is not merely changing the tasks within jobs—it’s changing the trajectories of careers. The traditional model of:

Entry-level → Gradual experience → Seniority

…is being replaced by a model in which:

Some roles require instant readiness, while others offer AI-accelerated entry

This reshapes the foundational architecture of talent development and professional growth. For employers, it requires rethinking how people learn, advance, and add value. For workers, it demands greater adaptability and self-directed growth.

Ultimately, the GenAI revolution is not about how many jobs disappear—but about who gets to learn, how fast, and what that learning is worth.
